Dear Stata users:
I have a question of how to set up the sampling plan using command svyset
for stratified multi-stage cluster sampling. I tried to look for every
source that I have, but could not figure that out. Hope that you can help
me out. Thanks!
Here it is:
The sample was obtained as follows. I sampled the population by
stratifying it first, and then I randomly selected several clusters for
each stratum. Within each cluster, I then random selected several
subclusters, and then for each subcluster, I randomly selected a certain
number of observations. for this sampling plan, how do I set up the
sampling plan using command svyset in STATA?
Would it be:
svyset [pweight = pwt], fpc(fpc) psu(cluster) strata(strata)?
I know this is for stratified TWO-stage cluster sampling plan, which is "
sample the populitation by strafifying it first, and then randomly select
several clusters for each stratum. Within each cluster, then randomly
select a certain number of observations."
Would the svyset for multiple-stage cluster sample (more than 2 stages)
with stratification be same as TWO-stage cluster sampling with
stratification?
More complicated is that what if I do cluster sampling first, and then
stratify each cluster, and then do cluster sampling again, what would
the command svy for settng up this sampling plan be?
Similarly, if I stratify the populaiton first, and then do the cluster,
and then do stratification again and then do cluster sampling again, what
would the svyset command be for this sampling plan?
To generalize the question, if we change the order of cluster sampling
and stratification sampling when sampling the populaiton, would the
svyset command be different?
Thank you very much!
Best regards,
Jian Zhang
